Streszczenie
Udomowienie zwierząt rozpoczęło się w neolicie, a dziś tylko kilka gatunków, takich jak bydło, owce, świnie i kury, stanowi podstawę produkcji żywności na świecie. Przemysłowa hodowla zwierząt doprowadziła do ogromnego wzrostu ich biomasy, która obecnie stanowi 60 proc. biomasy ssaków, podczas gdy biomasa dzikich zwierząt spadła dramatycznie. Przykładem tego jest kurczak, którego populacja liczy 22,7 miliarda osobników, co sprawia, że jest najliczniejszym ptakiem na świecie. Hodowla brojlerów, przeznaczonych głównie na mięso, ma znaczący wpływ na biologię tych zwierząt, prowadząc do patologii i skrócenia ich życia. Brojlery, całkowicie zależne od człowieka, mogą stać się markerem antropocenu, podobnie jak inne materiały antropogeniczne.
Abstract
The domestication of animals began in the Neolithic period, and today only a few species, such as cattle, sheep, pigs, and chickens, form the basis of global food production. Industrial animal farming has led to a massive increase in their biomass, which now constitutes 60 per cent of the biomass of mammals, while the biomass of wild animals has dramatically decreased. An example of this is the chicken, with a population of 22.7 billion individuals, making it the most numerous bird in the world. Broiler farming, primarily for meat production, significantly affects the biology of these animals, leading to pathologies and a shortened lifespan. Broilers, entirely dependent on humans, could become a marker of the Anthropocene, much like other anthropogenic materials.
